  • Patent number: 7339035
    Abstract: It is intended to provide an antibody efficacious in diagnosing, preventing or treating Alzheimer's disease, DNA encoding the antibody, a method of screening a drug and drugs. The amino acid sequence and the gene sequence of the variable region of an antibody, which specifically recognizes a GM1 ganglioside-bound amyloid ?-protein occurring in the early stage of ?-amyloid fibril formation, are determined. Based on the data of the amino acid sequence and the gene sequence thus obtained, an antibody is designed.

  • Patent number: 5356220
    Abstract: An optical fiber is laid in a spiral shape on a surface of an iron skin of a hot-air oven constituting a blast furnace facility, and one end of the optical fiber is connected to a temperature measuring apparatus. A temperature distribution of an optical fiber laid area is measured based on the intensity of Raman back scattering light of a light pulse transmitted into the optical fiber and based on a time interval until the Raman back scattering light returns to the transmission end of the optical fiber. The temperature distribution is displayed on a display screen to monitor the temperature distribution of the whole area of the iron skin of the hot-air oven to detect an abnormal condition thereof.

  • Patent number: 5320442
    Abstract: A liquid applicator structure which has an application tip fixed to front end of a cylindrical body and a liquid supply assembly built in its rear end. The liquid supply assembly includes a rotatable rod composed of a cylindrical shank-and-operating end and a solid rod having male threads thereon. The rotatable rod is held with an anti-rotation member having a cantilever-like extension. A split slide member having two split extensions is engaged with the rotatable rod at its rear end. One of these split extensions is inserted within the cantilever-like extension of the anti-rotation member and the rotatable rod, thereby preventing the split slide member from rotating. A piston member abuts on the split slide member. Rotation of the rotatable rod causes the split slide member and the piston to advance and drive liquid toward the application tip.
